OK, since we're extending this to include the range, I'll add.
Enough optics, one way or another, to clearly observe the the fall of each round.
I design and print my own targets, and this gives me the opportunity to print miniatures. These miniatures get adorned with marks and notes regarding loads, impacts, conditions, etc.; as the shots are fired.
Rather than bullseyes and groups, I design arrays of dots in rows and columns, 1/2" diameter for 100yd, heavy (9 pixel) black border around a field of bright yellow, for maxiumum contrast with the border and crosshairs, and to depict bullet holes most clearly. One shot per dot, every shot is distinct and portrayed in specific order, easily distanguished from the rest, and free from the need to perform any interpretations
I can contrast each shot separately, and combine the results to interpret them in terms of 1-shot, 3-shot, 5-shot, 10-shot, or even 15-shot groups, by measuring distances from target center for each one. Where situations and conditions permit, I will fire up to 15 rounds per load increment, because the larger the dataset, the more consistent the statistics will be relative to real-world shooting.
I don't really care about group sizes.
My key statistic is distance from POA. If you think about this, you will come to see a subtle but relevent difference.
BR shooters' grail is group sizes. Practical shooters' grail is distance from POA.
One of the key things I will note for each shot is whether it was on-call, or off-call. That helps sort the wheat from the chaff.
Shooting individual POA's refines the call process, and emphasizies its crucial importance.
I take personal mental note of my percentages of on-call and off-call shots, as a means of guaging my own performce while in the midst of guaging the system's performance. It's only fair to the gear, that the driver gets a score as well. Each is crucial to the process of marksmanship excellence; but unless we observe and note each, the process will suffer by the degree to which one neglects the one or the other.
